You can use the command mimeopen, in a terminal go to the folder where you have some pictures with extensions, you should do it for every extension. Suppose for picture named image.jpg. Run the command:

mimeopen -d image.jpg 

You will get a popup menu, where you can see some options, here is sample of my apps:

If mimeopen package not exists then you can install:

libfile-mimeinfo-perl

$ mimeopen -d e.jpg 
Please choose a default application for files of type image/jpeg

    1) Wine Internet Explorer  (wine-extension-jpe)
    2) Wine Internet Explorer  (wine-extension-jfif)
    3) gThumb  (gthumb)

    import sys
    import os
    from auth import Auth
    from printermanager import PrinterManager
    from ccputils import Utils

    # line below is replaced on commit
    CCPVersion = "20140814.2 000000"
    Utils.ShowVersion(CCPVersion)

    os.system("echo '%s' >/tmp/.c_mail"%mail_is)
    requestors, storage = Auth.SetupAuth(True)
    printer_manager = PrinterManager(requestors)
